i have fully comp on the car, and buildings and contents.
my view is, its not the point that you may never use it and pay out lots of money over the years, its there for the "just incase" . if my house collapsed because of subsidence, and i didnt have buildings, it is myself who would have to fork out for a new house or to rebuild my old one.
if i were robbed and my plasma, along with my vintage guitars and amps were stolen, if i did not have contents then it would be me again who would have to buy replacements at my own cost.
if i crashed my car which is worth 3 grand, i would have to spend another 3 grand to replace it or have it mended.
certain things might seem unlikely, but bad things can happen at any time and its nice to know your covered.
you might look back over the years and think "jesus ive spent thousands on insurance i never used" but in my opinion its worth being covered.
and plus, a condition of my mortgage is to have adequate buildings insurance anyhow.
